This week all of the green car news is focused around the growing number of hydrogen fuel cell vehicles that will soon hit the market. Following the announcements from Toyota and Honda earlier this week, Volkswagen has revealed its new Golf SportWagen HyMotion fuel cell concept at the 2014 Los Angeles Auto Show.

Unlike Toyota and Honda, which have unveiled completely different models for its fuel cell technology, VW is showing how its technology can be adapted to existing production models.

Volkswagen has been pretty quiet about the hydrogen fuel cell technology and hasn’t released any concepts with the technology since the Tiguan Hy-Motion back in 2008. The latest concept is based on the new Golf SportWagen, but is powered by the same hydrogen fuel-cell system as the Audi A7 h-tron concept that is also debuting at the LA Auto Show.

The Golf SportWagen HyMotion is powered by both a fuel-cell system and the same electric motor that powers the e-Golf. It has a range of 310 miles, but unlike traditional electric cars, this concept only takes up to three minutes to refuel with hydrogen. The concept also as the ability to act like a plug-in hybrid with a driving range of 31 miles in electric mode. The front-wheel-drive Golf SportWagen HyMotion accelerates from 0 to 62 mph in 10.0 seconds.

Where is the hydrogen stored? Compared to other models that store it behind the seat or in the trunk, the hydrogen in the SportWagen concept is stored safely in four high-tech carbon fiber tanks, which are located in the underbody, where they do not impede on interior space.
